    Boards arrived, time for testing everything

  • Testing signals

    Hardware works.

    X step signal

  • Remote interface - Cetus

    I managed to connect to the Beaglebone remotely via mklauncher and Cetus.

    The file can't be run, since beaglebone is not connected to real hardware and can't be homed.

    May be I will create a guide how to run it. Now it is something useful and I have to connect it to the steppers.

  • Available interfaces for the machinekit

    Machinekit can be started with different interfaces. They can be configured with setting DISPLAY variable in INI configuration file

    AXIS (unfortunately it crash, when I try to load a cut file):

    tkemc (this one seems to load OK, but refuses to run, since machine need to be homed first):

    There is also a few remote interfaces that need to be tested.

  • Progress so far

    My TinyG controller burned and can't be restored. Currently I set up an Arduino Uno with external drivers and GRBL firmware. My goal is to replace Arduino with Beaglebone Black, since only 3 axes are supported in GRBL.

    Conclusions so far:

    Beaglebone Green Wireless can't be used, because some needed pins are occupied.

    The machinekit image for the Beaglebone can be downloaded from:

    machinekit image

    I changed the image to be flashable (by changing uEnv.txt) and flashed it to the EMMC

    I use it with WiFi USB stick that can be configured as described here

    For the connection I use putty and Xming with X11 forwarding. In this way you don't need a display on the BBB. You see everything on your PC.

    I installed samba on the BBB and created a shared folder for quick files transfer.

    Machinekit can be run by simple command:

    machinekit

    I see the machinekit interface on my PC and I selected CRAMPS as an interface board.

    To be continued...

    My current setup - Arduino is going to be replaced, may be.
